Damping-off (Rhizoctoni solani) and Phytophthora spp.

Minor Pest Description

Damping-off of citrus is most often caused by Rhizoctonia solanispp. Phytophthora spp. The typical symptom of damping-off is dying of seedlings just after emergence from the soil. However, damping-off fungi can also cause seed rot, resulting in sparse stands of seedlings in nursery beds.


Minor Pest What to do.
  • Damping-off diseases are favoured by abundant moisture in the soil. Adequate control of damping-off diseases can be achieved by avoiding infested soils and overwatering.
  • In case of Phytophthora spp., seeds must be hot water treated. For more information on Hot water treatment click here.
  • Contaminated soil, tools or irrigation water should not be used in or near seedbeds.
